Rock stratum deep hole displacement monitor and quick mounting method

Abstract

The invention relates to a rock stratum deep hole displacement monitor and a quick mounting method. A detection device is arranged at the bottom of a rock stratum deep hole and is fixed on an elastic steel circular ring on the wall of the hole, the steel circular ring is fixed with a flexible steel wire extending to the outside of a hole port, and the roof plate displacement of a roof plate is measured according to the relative displacement between the hole port and the steel wire. The steel circular ring and the flexible steel wire are arranged on a drilling tool for mounting while drilling.The invention has the advantages that the monitor has a simple structure, is convenient to use, is finished through simple modification on a common drilling rod, and can adapt to rock stratum deep hole drilling and quick mounting; and the method can greatly improve the mounting speed and the efficiency, and has popularization and application prospects in the fields of mine laneways, road traffic tunnels, underground engineering, civil air defence, and the like.

Description

Rock formation deep hole displacement monitoring device and quick installation method technical field The invention relates to a rock formation deep hole displacement monitoring device and an installation method, in particular to a rock formation deep hole displacement monitoring device quick installation method. Background technique Mine roadway and stope roof control is one of the main contents of mine safety production. The deformation and displacement of roadway and stope roof will affect the safe production of roadway or coal mining face, and induce accidents. Immediately monitoring the displacement of the roadway and stope roof, and taking effective control measures to prevent serious displacement of the roof are effective methods to prevent roof collapse accidents. To monitor the displacement and deformation of the roof, the conventional method is to use a drilling rig to drill holes into the roof strata. During the drilling process, the multi-section drill pipes a...

Problems solved by technology

The disadvantages of this traditional displacement monitoring device installation method are: complex process, long installation time, after drilling a deep hole in areas with complicated geological conditions, the drilling hole will be deformed or collapsed due to the subsidence and deformation of the roof stratum Phenomenon: After the hole is drilled, due to the deformation or collapse of the hole, the extended drill pipe cannot enter the hole to install the displacement monitoring device, which makes it difficult and failed to install the displacement monitoring device in the hole.
